Most architecture and engineering firm owners get the succession timeline backward. They either assume they need five to seven years of elaborate planning, so they never start, or they assume they can exit whenever they decide, so they wait until they are burned out and out of options. The truth sits in between. A workable internal sale takes about three to four years of light preparation, counting down to the year you actually close.
Here is the timeline that fits an A/E or surveying firm selling to its own people.
Three to four years out: understand your options
This is where you map the paths available to you and learn what your firm is worth. You do not need a binder full of plans. You need to know whether a sale to your key employees is financeable, what a realistic valuation looks like, and which value drivers you can strengthen. Starting here gives you room to fix small things that move your multiple before it counts.
Two to three years out: identify your successors
Now you pinpoint the key employees who will carry the firm forward and begin preparing them. Who has the leadership to run the work? Who is ready to take on ownership? A smaller buying group of two or three people is often easier to finance and simpler to govern than trying to include everyone. This is also the window to strengthen the firm's independence from you personally, since a firm that does not depend on the owner sells for more.
One year out: execute and close
In the final year you put the financing and structure in place and close. Selling to key employees typically takes three to six months from the point the owner is ready to move, because the buyers already know the business. That is far faster than a third-party sale, which runs 9 to 24 months from the time you go to market.
Why most owners plan nothing, and why that is survivable
Here is the part no one says out loud: most owners do little or no succession planning, and when they sell to their employees, it usually still works. The reason is simple. Your key employees have watched the firm perform for years. They know the clients, the projects, and the risks. Their due diligence is far lighter than an outside buyer's, because there is nothing hidden from the people already running the work. An outside buyer has to investigate everything. Your team already knows it.
That does not make planning worthless. Starting three to four years out gives you more options and a higher number. But if you are closer to the exit than that, a sale to your employees is still very much on the table.
The advantage of an internal sale
The Step-Up Legacy Plan is built around this reality. A bank finances the purchase, your employees buy in with as little as 5 percent down, and you receive 95 to 100 percent of your proceeds at closing. The shorter timeline is not a shortcut. It is the natural result of selling to buyers who already know exactly what they are buying. If retirement is anywhere on your horizon, look at what selling to your key employees would take.
